yep. as info, my engine is a 2316cc with 9.7:1. that "up hill" was literally about 1 mile or so at 20% grade or so (guestimates here) at around 80-90MPH and high RPM (i'm geared for acceleration). my oil temp gauge was not hooked up though to know what oil temps looked like. based on load hits head temps and RPM hits oil temps, i was VERY pleased with the head temps.
really looking forward to your info Sandeep. especially on head temps on a relatively stock engine with the FAT shroud. although not a favorite for cramming in a bug, it is the easiest (really only) retro fit 911 system out there and probably the most affordable. great way for low budget projects that just have to have the 911 system to get a running stock TIV in their bug.
